lMPROVENIENT IN GRAIN AND GRASS HARVESTERS.

Specilcation forming part of Letters Patent No. 13,330, dated July 24,1855i.

' To all 'whom '1' t may concern.'

` De it. known that I, JESSE URMY, of Wilmington, in the count o t' NewCastle and State of Delaware, haveinvented certain Improve?, ments inReaping and Mowing Machines and I do hereby declare that the followingis a full, clear, and exact description of the principle or characterwhich distinguishes it from all other things before known, and of theusual nianncr of making, modifying, and using the same, referencebeinghad to the accompanying.r drawings, of .which- Figure 1' represents aplan of my reaper and mower; Fig. 2, a side view, showing the gearing,Src.; Fig. 3, a side view of my 'partingboard Fig. 4, a front viewA ofthe dogs b b; 'Fig'. 5, the gearing, and shows the mode of adjustment;Fig. 6, a perspective section and side view ot the cutting arrangement.l n My invention consists in certain improvements'ir machinesi'or'reaping and mowing, hereinafter described, as follows: In' thismachine thereciprocating motion isA given to the cutter-bar by means ot'a rod, h,'which on one end is fastened to the cutter-bar; thence reachesback and around the driving-wheel c, where its other end connects wlth acrank, c.

.This crank is fast on the axis ot' bevel-wheel b. which gears intobevel-wheel c. This axis "a' a' of this last bevel-wheel a carries onits inner end a cog-wheel, which gears into the axis a a is supported bya crank-lever, 61 `which is pivoted to the frame d in rear of thedriving-wheel and'b'eveh gearing, the front end of said crank-leverreaching underneath the drivers seat,where it is pivoted to the lowestarm of a three-armed lever, b b b. -The fulcrum of this three-armedlever is about in itscenter, andthe driver, by pressing his foot ontheone or the other of the upper' two arms of lever b b', causesthelohwer a'rm'to describe a semicircularway"e round its fulcrum,thereby movingj in or out the front end Yot' crank-,lever d, and with itofcourse the central part of'said crank-lever which carries the outerend ofaxle a' a'. 'By these means the bevel-wheel cca-n be brought intoor out of gearingwith bevel-wheel b, thereby either vofthe standinggrass, an'd it is attached tov the part et' the frame nearest to thecutting machinery by means ot' a bent bar, t', in order to prevent' sidedraft.

Another feature ofthe machine consists in the arrangementof the rake lt.The rakeeis attached to the rearend of a horizontal rod,

m, which is pivoted in 'm' to -an eccentric, t'. The front end of rod mhas` aslot in which plays a pin, h'yrv'hich'extevuds upward ironr'a slotin a secondary horizontal rod, n. This rod 1t ispivotcd to the trameabout in its center, and itsend a3 opposite vto the end which carriespian is .provided with a frictionroller which plays in the groove oi" aneccentric, t',

below the veccentric--abov'ementioned. '.lhe' revolution of thedoubleeccentric 't' t', in coinbination with the said arrangement o f theadjust-able rods m and laimparts to the rake its proper motion. Anadjustable plate, k, serves to increase or' decrease thecccentgicityofthe upper eccentric, i, thereby giving therakc more orless range of action. axis of the double eccentric-tz' is revolved bymeans of a pinion, l', which can be properly elevated or depressed, soyas tofmake it gear into either one of the concentriesets ot' cogs' ppon the inner face ofthe drivingwheeh thereby augmenting or diminishingthe velocity of the motion of the rake. 1n rear of the driving-wheel,and on the outer side of the rake, there is hinged to the frame aguardboard, s, which is to prevent the grass from being thrown round bythe rake under the driving-wheel. ,The dividing-board fis hoi-i.:

zontally hinged, sothat its inner edge Gambe.

more or less turned from a vert-ical towarda horizontal position,therebyT gathering ntthe grain or grass more or less.closely. There isfastened to this vibrating cntter-bar a plate,

f', the rear partof which lies at and slides The vertical 2 reges@ onthe fingerboard in order to keep theSa-ine clear. The upper sides of thefinger-slots are provided With concave bed-plates w, their concave sidesbeing placed toward the knives. The knives t are also curved, instead ofbeing tial, and their concave surfaces are placed toward the concavesofthe bed-plates w. Knives and bed-plates are on their edges in closecontuct, so that the;T will continually 'sharpen each other.Thefbed-plates are adjustable, so as to make up for the Wearing of theplates and knives. and 'to keep them always in proper contact. Thesebed-plates w are shoe-pieces ot' steel, which ma)` be taken out andsharpened or adjusted when necessary. 'lhe concave guard z in the rearof the bed-plates has projecting guides y y, between which passprojecting plate ir, ,upon the rear of theknives t, for the purpose'ofclearing out the grass and dirt which may lodgevthcre.

What I claim as my improvements in reapers and mowers is'- 1. Incombination with the driving-wheel placed inside the gearing, as abovedescribed, the angular tongue t', for preventing sidedral't and at thesame time allowing the horses to walk on the side of the standing grassorgrain.

2. The above-described use 0l' the balanced dogs b b under the drivel-7sfeet for throwing the cutting apparatus in and outJ ot geare 3. Makingthe parting and gathering board fhinged and adjustable, as set forth.

4. Regulating the size ot' the sheaves by means ot' the several rangesof gearing p1) :within the driving-Wheel, in combination with theadjustable pinion r, as set forth.
